The thermal design of electronic products may employ passive techniques in the form of conduction, radiation or natural convection, or may employ forced air cooling, heat exchangers or active techniques that circulate a cooling fluid. The active cooling liquid circulation technology is used for carrying out heat exchange specifically by using a water cooling system, the water cooling system generally comprises a water cooling plate, a water pump, a water tank, a heat exchanger and a fan, the power generated by the water pump is used for pushing the liquid in the water cooling system to circulate, the heat generated by the electronic product is taken to the heat exchanger with larger area through the circulation of the liquid for heat dissipation, the cooled liquid flows back to the water cooling plate again, and the circulation is repeated.
In the water cooling system, the water cooling plate is used as a heat absorbing part which is directly contacted with the electronic product, so how the quality of the water cooling plate directly affects the heat dissipation effect of the water cooling system. Wherein, the water-cooling board includes base plate and water-cooling tube, disposes the mounting groove on the base plate, and the water-cooling tube configuration all disposes the water-cooling joint on the mounting groove, for avoiding leaking, disposes the sealing washer in the water-cooling joint, and at present, the manufacturing process of water-cooling board is like:

The method easily causes the sealing performance failure of the water-cooling joint because the soldering paste is heated at high temperature, has low product percent of pass and high cost (the soldering paste is expensive), and causes the heat resistance of the water-cooling plate to be larger and the heat dissipation effect to be poor because the heat dissipation coefficient of the soldering paste is low.

The water-cooling plate processed by the method has the following problems: a gap exists between the water-cooling pipe and the mounting groove, so that the thermal resistance is large and the heat dissipation effect is poor; the water-cooling pipe is easily by the extrusion deformation, leads to the area of contact between water-cooling board and the electronic product to reduce, influences the radiating effect, more importantly, if sunken in the middle of the water-cooling pipe, and sunken then can lead to unable conduct heat source face when comparatively serious.
